Search & Filtering
Create a maze without itertools and copy library Assign them (2, y) coordinates, where (0,0) is the upper-left corner of the map. In the example map above, we have lots of cells along the top edge; their coordinates are (0,0), (1,0), (2,0),(3,0),(4,0), (5,0),(6,0),... There are also quite a few along the left edge: (0,1),(0,2), (0,3), (0,4),(0,5).... The start point is at (4,0) and the end point is at (5,7). Required Dump Points As noted above, the "command" that the user types will tell you how far to run the algorithm, before you dump out a result. You must support the following commands; if the user types anything other than one of these (a blank line is OK), then report an error and terminate the program. For each of these commands, check the testcases to find the proper output.
Write a program that has these overloaded search methods to do array searching:
boolean search(int[] arr, int searchKey) – searches an integer array given a search key value, returns true if searchKey is found, false if not.
Hint:
boolean found=false;
for(int i=0; i<arr.length; i++){
if( ){//compare the array element with the search key value
//action taken if found
}
}
//return something
boolean search(String[] arr, String searchKey) – searches an array of strings given a search key value, returns true if searchKey is found, false if not.
(read Comparing_Strings.doc)
In the main method, you can declare and initialize the two arrays with random values, for example:
int[] intArray={7,3,2,8,1,0,9};
String strArray={"Enchanted","Bedazzled","Divine","Delighted","Elegant"};
Use the methods in the program.
Enter a string to search in the array: bedazzled
bedazzled is found in the array
Write a program that can perform addition with these overloaded methods:
int add(int x, int y) – returns the sum of two integer values
double add(int x, double y) – returns the sum of an integer value and a double value
double add(int x, int y, double z) – returns the sum of two integer values and a double value
Use the methods in the program. (How would you use them?)
What happens if there are no policies about the legal and ethical issues of media and information?
Suppose that we know f(x) is a polynomial with critical points x=-1, x=2 and x=6. If we also that the 2nd derivative is f''(x) = -3x² +14x -4. If possible, classify each of the critical points as relative minimums, relative maximums. If it is not possible to classify the critical points clearly explain why they cannot be classified.

Write a program to take input for n book records from user and write those book records in a file named: ”record”, whose price is less than INR 500 . Program should also perform random access in the file, after taking input for a particular record number to read and it should also perform random record overwriting after taking input of new record and the record number to overwrite. After overwriting record, display all records on the screen [Attributes of book: Book_id, Book_price, Book_name, Book_author_name]
Write a program to take input for n number of doctor records and write records of all cardiologists in
a file named: “record1”. Also write records of all those doctors in another file named: “record2” who are
taking salary more than INR 80,000. After writing records in both files, merge their contents in another
file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of doctor:
doc_id, doc_name, doc_specialization, doc_salary]
